[Asterisk-Users] restructuring my dialplan

[Rich Adamson]

I'm in the process of restructuring my complete dialplan. It contains
several contexts like:

[from-sip]
include => local-extns
include => local-calls
include => bus-dialing  ; 9 plus anything outbound
include => misc-extns
include => parkedcalls
include => zaptel700
include => livevoip-ld
include => special-3digit

[trusted-remotes]
include => local-extns
include => local-calls

; This section for 311, 411, 511, 911, etc.
[special-3digit]
exten => _X11,1,Dial(Zap/3/${EXTEN})
exten => _X11,2,Congestion

Should each include section include an "i" extension, or is it more 
appropriate to define yet another context like "call-failed" (at 
the end of the above) and include an "i" extension there?
